COUPLING F03 PONTOONS AND THE LIKE.

Specification of Letters Patent.

Patented Apr. 18, 1916.

Application filed April 13, 1914. Serial No. 831,594.

To all whom it may concern Be it known that 1, JOHN SHARP, a subject of the King of Great Britain, and resident of 26 Borden street, inthe city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented new and useful Improvements in Couplings for Pontoons and the like, of Which the following is a specification.

The invention relates to improvements in couplings for pontoons and the like as described in the present specification and shown in the accompanying drawings that form part of the same.

The invention consists essentially in the novel construction and arrangement of parts whereby a flexible connection is established between the pontoons.

a coupling which will not prove a rigid re-- sistance to the movements of the pontoons subsequent upon the unrest of the water, to effect a very secure joint between the floats and generally to provide a simple, cheap, durable and eflicient coupling.

In the drawings,Figure 1 is a plan view of portions of pontoons showing a top view of the coupling. Fig. 2 is a side elevation of the arrangement shown in Fig. 1. Fig. 3 is a perspective detail of a coupler member. Fig. 4 is a perspective detail of the other coupler member. Fig. 5 is a detail showing a plan view of the link. Fig. 6 is a detail showing a side elevation of the link. Fig. 7 is a detail of a pin. Fig. 8 is a detail of the spring.

Like numerals'of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is a coupler member having the sides 2, suitable bolt holes 3 through said sides, the web 4 reinforcing said sides tapering on each side from the center 5 to the ends 6, the webs 7 reinforcing the outer end 8 and at right angles to the-web 4 and the lugs 9 and 10 having the pin holes 11 therethrough.

12 is a coupler member of exactly similar formation with the exception that the lugs 13 and 14 extend from the end 15 and are at right angular arrangement in relation to the lugs 9 and 10 of the other coupler member so as to form a flexible joint.

16 are the links each of said links being substantially U-shape, each arm of the U terminating in the eyes 17, and the inside facing of the U having the boss 18.

19 is a spiral spring held between the bosses 18 and encircling said bosses.

20 are pins having the heads 21, said pins being inserted through the lugs 9 and 10 and the one pair of eyes 17, and through the lugs 13 and the other pair of eyes 17 thus joining the coupler member 1 to the coupler member 12 with the spring forming a cushion inside the link members, while the setting of the lugs provides additional flexibility.

22 are washers at the lower portion of the pins held by the cotters 23.

The coupler members 1 and 12 are rigidly secured to the pontoons and coupled up by means of the link and pin members, then the pontoons are free to swing reasonably and bob around notwithstanding being joined together, therefore the roughness of the water will not have the effect of parting the coupling.

What I claim is 1. In a coupling for pontoons and the like, a pair of coupler members having an outer end wall, and side walls projecting inwardly from said outer end wall and lugs extending from the ends of said side walls having pin holes, those of the respective lugs being in planes at right angles to each other, link members substantially U-shaped and having eyes registering with said lugs, pins joining said lugs and eyes, and a resilient member within said links.

2. In a coupling for pontoons and the like, a pair of coupling members having lugs projecting forwardly therefrom, the lugs of one being at right angles to the lugs of the other, a pair of link members having eyes registering with said lugs, pins joining said links and members, and a spring within said links and compressed thereby.

3. In a coupling for pontoons and the like, a pair of coupler members each having substantially parallel walls extending inwardly from an outer end wall and lugs extending from said end wall, the lugs of one being at right angles to the lugs of the other, a pair of U-shaped link members having the arms of the Us terminating in eyes adapted to register with said lugs, pins joining said eyes and lugs and a spring within said link members.

4. In a 'couplirig'for pontoons 'and the like, and arranged .therebet'ween an'ZLpins joina pair of coupler members having side and ing said eyes and lugs. 10
